Não sei se entendi direito, mas pelo que entendi, Christopher O’Leary criou uma escultura baseado em dados obtidos utilizando crawns na web e depois categorizando os 100 termos que mais aparecem pela CDD.

Confiram vocês mesmos a descrição dele sobre a escultura:

2007 Plexiglass Sculpture, collaboration with Casey Alt.

In The Future 100×100 is a data sculpture which visualizes 100 years of forward thought. Using web-crawls of Google News, Google Blog and Google Scholar, the phrase “in the future” was associated with key words and phrases which reveal previous though about the future of our world. The top 100 terms for each year were categorized using the Dewey Decimal system, and mapped onto a grid. Holes were drilled into sheets of plexiglass whose sizes correspond to their frequency. For example, “war” is the biggest hole in 1945. The prototype shown here is a sketch for a larger installation.
